Portfolio overview

Greenfield Specialty Alcohols Inc. has been granted 17 US utility patents between 2015 and 2020, placing Greenfield Specialty Alcohols Inc. at rank #16,821 across all assignees tracked by PlainPatent. This portfolio spans 17 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.8 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Greenfield Specialty Alcohols Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Greenfield sits between Genexine, Inc. (17 patents, rank #16,817) and Guizhou Baishancloud Technology Co., Ltd. (17 patents, rank #16,825) - the closest US assignees by grant volume. The composite Innovation Score of 34.7/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 2 grants, compared with 15 in the 2015–2019 window, a -87% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Greenfield Specialty Alcohols Inc.'s 16.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 17 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Greenfield Specialty Alcohols Inc. against peers pursuing similar technology classes.
